Hi
For your first question:
You can use
WinJS.Binding.List object to store your data.
Then use
WinJS.Binding.as to bind the Data to a Winjs.Namespace.
For example:
//define the data namespace.
(function () {
"use strict";
var shoppingItemsList = new WinJS.Binding.List();
var preferredStoresList = new WinJS.Binding.List();
WinJS.Namespace.define("ViewModel", {
UserData: WinJS.Binding.as({
homeZipCode: null,
getStores: function () {
return preferredStoresList;
},
addItem: function (newName, newQuantity, newStore) {
shoppingItemsList.push({
item: newName,
quantity: newQuantity,
store: newStore
});
}
})
});
// statements to add test data removed for brevity
})();
//add data to the namespace
ViewModel.UserData.addItem("Ice Cream", 1, "Vanilla", "Walmart");
The WinJS.Binding.as method replaces data properties with getters and setters that trigger
notifications when the property value change.
For the second:
Can you explain it clearer？
